Viewing annotations
The annotation area below each image in the Save for Web dialog
box provides valuable optimization information. The annotation for the original image
shows the filename and file size. The annotation for the optimized image shows the
current optimization options, the size of the optimized file, and the estimated download
time using the selected modem speed. You can choose a modem speed in the Preview
pop-up menu.
Working with slices in the Save for Web dialog box (Photoshop)
If your artwork contains multiple slices, you must specify the slices to be optimized. You
can apply optimization settings to additional slices by linking the slices. Linked slices in
GIF and PNG-8 format share a color palette and dither pattern to prevent the appearance
of seams between the slices.

Click the Toggle Slices Visibility button
